TC, you can make as much sense as you want, but it ultimately comes down to this. The "competitive" community only wants Melee. Smash 4 is not Melee. Therefore, the days of Smash 4 in the current "competitive" community are numbered. There was never any question that the people who have heavily invested in Melee for more than a decade would choose it over anything else that came out, no matter how balanced the roster or deep the meta.
That said, if you want to create a NEW competitive community, then you might have a chance. There are alot of players like me who get no entertainment from watching five thousand Foxes dash dancing around each other, looking for a twitchy opportunity to land a shine spike combo. I'm more impressed by creativity and strategy, and this game offers the potential for loads of it. I'd like to see us break away from the "lifeless stages only" attitude and bring in some of the crazy ones. If the players can't handle that and camp on walk-offs like little *******, then make a "no camping on walk-offs like a little *****" rule. We did it for planking. I'm also in favor of items for some tournaments. Yes, they dramatically alter a match, but that's precisely WHY I like them. No two matches are the same. Can you even tell the difference from one Zero vs Hungrybox match to the next? It's exciting to see someone get totally screwed, fight as hard as they can against the odds (literally), then finally get a chance at a big comeback in the final moments.
I don't think every tournament should be the wild west with stages and items. I think that the current format (no items, static stages) and a new format (items, crazy stages) are equally important. In fact, I want there to be even more formats (custom moves, equipment, etc). I'd like to see people show their skill in all aspects of the game, not just some tiny little fragment.
Finally, I really think we need to do away with double elimination. It takes an insanely long time to finish even a small tournament, and you spend much more of it waiting than actually playing. It's exhausting, and I admit that I actually feel less like playing Smash for a while after a tournament when I should feel pumped up instead. I think that for local tournaments, the Swiss system would be far superior (more games for every player, better assessment of player skill). For big showy tournaments, high stakes single elimination is exciting and easy to watch in a single sitting.
